Hey KWA community,
I was wondering if anyone had the technical numbers on certain parts.  I have read up on the KWA gears and how they have evolved and am very impressed. A few of my buddies have KWA guns and they are rock solid so I thought i'd do some digging on the forums.  I want to upgrade some gears for higher torque application.  The gears in the pro shop say they are torque gears but I didn't see any gear ratio information listed or around the forums. Also I was wondering about the KWA motor torque numbers.  What are the rpms, what spring size can it safely pull.  

I am looking into these gears for both v2 and v3 gearbox applications. Any information would be helpful as well as any compatability issues there might be when using KWA parts listed above in Classic Army, Ares, Tokyo Marui guns.
Thanks a bunch,
Adam

KWA gears are proprietary to KWA guns.

In what way are the gears proprietary?  Is is possible to modify my existing gearbox to accommodate the gears?  Also I am still curious of the gear ratio and torque specifications of the motor.

Gear ratio was posted in another thread awhile back, try searching for the thread and I'll do the same.

Well I did some more in depth searching on the forums, and the best I could come up with was that KWA gears can handle 150 springs, and are stock ratio.  Which I suppose answers the question to some extent. I suppose that also assumes that the motor can handle a 150 spring as well.  I did come across a few threads on compatibility but suggestions were made to query on the Classic Army forums for compatibility.  If anyone has experience at all in placing KWA gears in no KWA guns I would appreciate the insight.  What specifically makes them proprietary.  I will continue my search but would appreciate if someone could offer me a shortcut. Thanks

No the stock KWA motor might get 5 bps with a big enough battery on an M150. Do yourself a favor and if you get an M150 spring get a neodymium magnet motor.

5bbps is not a huge deal.  I am doing my best to construct a DMR out of a CA g3.  I really appreciate the quality gone into the KWA parts hence why I would like to try to use them.  The best I have come up with is that the sector gear is bigger on KWA stuff, and some people say that there is issue with v7 gearboxes.  I cant for the life of me find anyone who says it works.  Guarder gears are about the same price but I like seeing the quality in the KWA (based on forum posts of the evolution of gears).

18.72:1.  You can calculate this yourself by counting the teeth of each gear

The gears are made with spacers into the axis that in combination with the bearing bushings negates the need for regular shimming.  As such, an aftermarket gear set will require serious fitting to accommodate the large bearing bushings.

just to tell you now, i tried the same thing as you for a very long time, working to get a G3 to be a DMR, and that thing simply never performed the way i wanted it to, the G3 has a free floating and lose hop up which created inconsistency in the shots, also the hop up has seal issues. i tried for years to get a good DMR our of my G3, but it just could never compete with other guns. it worked well, dont get me wrong, but i was going for a high-performance out range the other guy gun, and it just couldn't deliver. maybe you'll have better luck, but just a heads up. now my KM-16 on the other hand... i love the fact that i hit people who are just standing because the think they are out of range...
